我是靠谱客的博主 标致枫叶,最近开发中收集的这篇文章主要介绍Centos6.5 64+oracle11.2.0.4+rman 搭建物理DG,觉得挺不错的,现在分享给大家,希望可以做个参考。

概述

1环境列表

名称

主机1

主机2

主机名

orcl

orcldg

ip

192.168.204.210

192.168.204.211

2分别配置主机环境

2.1配置主机名

临时生效 hostname  name

永久生效vi /etc/sysconfig/network

2.2配置/etc/hosts 文件

添加

192.168.204.210    orcl

192.168. 204.211   orcldg

2.3配关闭防火墙,设置静态IP等(service   network   restart)

chkconfig iptable off

vi   /etc/selinux/config 

sestatus

3主机1与主机2都安装oracle11.2.0.4数据库软件(略)

参考http://blog.csdn.net/sunziyue/article/details/49100593

4主机1利用DBCA工具创建实例orcl,主机2暂时不用配置实例(如果是windows,恢复前需要oradim  -NEW -SID orcldg 创建新实例)。

4.1主机1 oracle用户环境变量vi  /home/oracle/.bash_profile

PATH=$PATH:$HOME/bin

export PATH

export ORACLE_BASE=/u01/app/oracle

export  ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1

export  ORACLE_SID=orcl

export  PATH=$ORACLE_HOME/bin:$PATH

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib64:/usr/lib64:/usr/local/lib64

4.2主机2 oracle用户环境变量vi  /home/oracle/.bash_profile

PATH=$PATH:$HOME/bin

export PATH

export ORACLE_BASE=/u01/app/oracle

export  ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1

export  ORACLE_SID=orcldg

export  PATH=$ORACLE_HOME/bin:$PATH

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib64:/usr/lib64:/usr/local/lib64

5准备工作

配置主机1,主机2上数据库静态监听,网络服务名,使互相可以tnsping

涉及命令netca,netmgr, tnsping

主机1

listener.ora

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (GLOBAL_DBNAME = orcl)

      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)

      (SID_NAME = orcl)

    )

  )

LISTENER =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = orcl)(PORT = 1521))

  )

ADR_BASE_LISTENER = /u01/app/oracle

tnsnames.ora

ORCL =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = orcl)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = orcl)

    )

  )

ORCLDG =

  (DESCRIPTION =

    (ADDRESS_LIST =

      (ADDRESS = (PROTOCOL = TCP)(HOST =orcldg)(PORT = 1521))

    )

    (CONNECT_DATA =

      (SERVICE_NAME = orcldg)

    )

  )

主机2中listener.ora与tnsnames.ora同理配置

5搭建DG—按以下顺序操作

5.1主库操作

设置归档:alter database archivelog;

设置强制记录日志:alter database force logging;

oracle用户创建归档路径:mkdir  -p /u01/app/oracle/archivelog

oracle用户创建备份路径:mkdir  -p /u01/app/oracle/databack

更改归档路径:alter system set log_archive_dest_1='location=/u01/app/oracle/archivelog';

主库创建参数文件,口令文件,dg控制文件拷贝到备库相同路径

create pfile from spfile;

--如果不创建,直接拷贝/u01/app/oracle/product/11.2.0/db_1/dbs/下的orapworcl文件

orapwdfile='/u01/app/oracle/product/11.2.0/db_1/dbs/orapworcl' password=123456 force=y

alter database create standby controlfile as '/u01/app/oracle/databack/standby.ctl';

从主库所在服务器远程拷贝到备机:(拷贝之前备机有必要先创建路径文件)

scp   initorcl.ora  orcldg: /u01/app/oracle/product/11.2.0/db_1/dbs/

5.2备库操作

创建必要文件路径:

[oracle@orcldg ~]$ mkdir -p  /u01/app/oracle/admin/orcldg/adump

[oracle@orcldg ~]$ mkdir  -p  /u01/app/oracle/fast_recovery_area/orcldg

[oracle@orcldg ~]$ mkdir  -p /u01/app/oracle/archivelog

[oracle@orcldg ~]$ mkdir  -p /u01/app/oracle/databack

[oracle@orcldg ~]$ mkdir -p /u01/app/oracle/oradata/orcldg/

修改备库参数文件(主库参数文件的重命名得到)

vi  initorcldg

修改参数以及添加以下参数

下列参数为primary 角色相关

*.db_unique_name='orcldg'

*.log_archive_config='dg_config=(orcl,orcldg)'

*.log_archive_dest_1='location=/u01/app/oracle/archivelog valid_for=(all_logfiles,all_roles)

db_unique_name=orcldg'

*.log_archive_dest_2='service=orcl  lgwr sync affirm

 valid_for=(online_logfiles,primary_role)  db_unique_name=orcl'

*.log_archive_dest_state_1=enable

*.log_archive_dest_state_2=enable

*.log_archive_max_processes=10

以下参数为主库转为standby 角色时需要配置相关的参数

*.db_file_name_convert='/u01/app/oracle/oradata/orcl', '/u01/app/oracle/oradata/orcldg'

*.log_file_name_convert='/u01/app/oracle/oradata/orcl', '/u01/app/oracle/oradata/orcldg'

*.fal_server=orcl

*.fal_client=orcldg

*.standby_file_management=auto

最后参数文件为:

orcldg.__db_cache_size=306184192

orcldg.__java_pool_size=4194304

orcldg.__large_pool_size=8388608

orcldg.__oracle_base='/u01/app/oracle'#ORACLE_BASE set from environment

orcldg.__pga_aggregate_target=314572800

orcldg.__sga_target=469762048

orcldg.__shared_io_pool_size=0

orcldg.__shared_pool_size=138412032

orcldg.__streams_pool_size=4194304

*.audit_file_dest='/u01/app/oracle/admin/orcldg/adump'

*.audit_trail='db'

*.compatible='11.2.0.4.0'

*.control_files='/u01/app/oracle/oradata/orcldg/control01.ctl','/u01/app/oracle/fast_recovery_area/orcldg/control02.ctl'

*.db_block_size=8192

*.db_domain=''

*.db_name='orcl'

*.db_recovery_file_dest='/u01/app/oracle/fast_recovery_area'

*.db_recovery_file_dest_size=1239416832

*.diagnostic_dest='/u01/app/oracle'

*.dispatchers='(PROTOCOL=TCP) (SERVICE=orclXDB)'

*.log_archive_format='%t_%s_%r.dbf'

*.memory_target=783286272

*.open_cursors=300

*.processes=150

*.remote_login_passwordfile='EXCLUSIVE'

*.undo_tablespace='UNDOTBS1'

*.db_unique_name='orcldg'

*.log_archive_config='dg_config=(orcl,orcldg)'

*.log_archive_dest_1='location=/u01/app/oracle/archivelog valid_for=(all_logfiles,all_roles) db_unique_name=orcldg'

*.log_archive_dest_2='service=orcl  lgwr sync affirm valid_for=(online_logfiles,primary_role)  db_unique_name=orcl'

*.log_archive_dest_state_1=enable

*.log_archive_dest_state_2=enable

*.log_archive_max_processes=10

*.db_file_name_convert='/u01/app/oracle/oradata/orcl', '/u01/app/oracle/oradata/orcldg'

*.log_file_name_convert='/u01/app/oracle/oradata/orcl', '/u01/app/oracle/oradata/orcldg'

*.fal_server=orcl

*.fal_client=orcldg

*.standby_file_management=auto

启动数据库到nomout:  startup   nomout  pfile='/u01/app/oracle/product/11.2.0/db_1/dbs/initorcldg.ora'

创建spfile:create spfile  from pfile

利用spfile文件再次启动数据库到nomout: shutdown immediate 与 startup   nomout

备库操作暂时结束

5.3再次主库操作

动态参数:

alter system set log_archive_config='dg_config=(orcl, orcldg)';

alter system set log_archive_dest_1='location=/u01/app/oracle/archivelog valid_for=(all_logfiles,all_roles) db_unique_name=orcl';

alter system set log_archive_dest_2='service=orcldg lgwr async valid_for=(online_logfiles,primary_role) db_unique_name=orcldg';

alter system set log_archive_dest_state_1=enable;

alter system set log_archive_dest_state_2=enable;

alter system set log_archive_max_processes=10;

alter system set fal_server=orcldg;

alter system set fal_client=orcl;

alter system set standby_file_management=auto;

静态重启生效参数:

alter system set db_unique_name='orcl' scope=spfile;

alter system set db_file_name_convert='/u01/app/oracle/oradata/orcldg','/u01/app/oracle/oradata/orcl' scope=spfile;

alter system set log_file_name_convert='/u01/app/oracle/oradata/orcldg','/u01/app/oracle/oradata/orcl' scope=spfile;

可以不重启开始备份主库:

rman  target  /

backup database   format '/u01/app/oracle/databack/%U';

拷贝到备库相同目录下

scp   备份文件   orcldg:/u01/app/oracle/

5.4主库执行以下命令完成dg搭建:

rman target / auxiliary sys/XXXX@orcldg

duplicate target database for standby;

5.5完成后,dg已经搭建完毕,但是只支持最大性能模式,如果要支持最大保护模式需要创建standby logfile,备库执行

alterdatabase add standby logfile  group 4('/u01/app/oracle/oradata/orcldg/redo_04.log') size 50m;

alterdatabase add standby logfile  group 5('/u01/app/oracle/oradata/orcldg/redo_05.log') size 50m;

alterdatabase add standby logfile  group 6('/u01/app/oracle/oradata/orcldg/redo_06.log') size 50m;

alterdatabase add standby logfile  group 7 ('/u01/app/oracle/oradata/orcldg/redo_07.log')size 50m;

为了以后主备库切换,而支持最大保护模式,所以主库最好也创建

alterdatabase add standby logfile  group 4('/u01/app/oracle/oradata/orcl/redo_04.log') size 50m;

alterdatabase add standby logfile  group 5('/u01/app/oracle/oradata/orcl/redo_05.log') size 50m;

alterdatabase add standby logfile  group 6('/u01/app/oracle/oradata/orcl/redo_06.log') size 50m;

alterdatabase add standby logfile  group 7('/u01/app/oracle/oradata/orcl/redo_07.log') size 50m;

到此搭建完成。
